BOTTLE-FILLING MACHINE.

SPECIFICATION forming part 'of Letters Patent No. 531,717, dated January 1, 1 895.

Application tiled April 19 1894- To all whom it maypcanccrnf.-

Be it known that we, GEORGE CLAUss, Jr., of Elizabeth, Union county, and ALBERT M. SCHOMBURG, of Newark, county of Essex, New Jersey, have invented certain new and useful Improvements in Bottle-Filling Machines, of which the following is a specification.

The invention relates to bottle filling machinessuch as shown and described in the Letters Patent of the United States, No. 482,894, granted to us under date of September 20,1892.

The object of the present invention is to provide a new and improved bottle filling machine arranged in such a manner as to insure the proper iilling of bottles with beer or other liquids and without waste of the liquid.

The invention consists in various parts and details and combinations of the same, as hereinafter more fully described, and pointed out in the claims.

Reference is to be had tothe accompanying drawings, forming a part of this specification, and in which similar letters of reference indicate corresponding parts in all the views.

Figure lis a sectional front elevation of the improvement. Fig. 2 is an enlarged sectional elevation of a' bottle and the lling device therefor. Fig. 3 is an enlarged sectional plan view of the filling device on the line 3. 3. of Fig. 2, and Fig. 4 is an enlarged sectional side elevation of one of the oat valves.

The improved bottle filling machine is'provided with a number of posts A on which is held adjustably a platform B adapted to receive a tray C carrying the bottles D to be filled, the said platform and tray being similar in construction as the ones shown and described in the Letters Patent above referred to so that further description of the same is not deemed necessary.

In the platform B are fitted to slide the vertically extending guide rods E supporting at their upper ends the tank F adapted to contain the liquid to be filled into the bottles on the tray C, the said tank being provided with suitable means for filling itand with devices for raising and lowering the tank. The latter is properly counterbalanced by ropes or chains E and connected with the lower ends of the guide-rods and passing over pulleys E2 j ournaled in brackets on the underside of the Serial No. 508,177. (No model.)

tilling pipe is formed with a valve seat G adapted to be engaged by a weighted valve H held on a rod H extending downward through the corresponding iilling pipe. The rods H are of such length relative to the filling pipes G that when the several parts are in the position shown in Fig. l and the valves H are seated on their seats G then the extreme lower ends of the rods project a suitable distance below the lower ends of the filling pipes G. Now when the tank F is lowered the filling pipes G pass into the bottles and the projecting ends of the rods H finally strike the bottoms of the bottles so on a further downward movement of the said tank F the rods l-I are held stationary and the valves H are unseated to permit the liquid to iicw from the tank F through the filling pipes G into the several bottles D.

In order to permit a proper escape ot' the air contained in the bottles D on lling the same with the liquid, the following device is provided: On each filling pipe G is held loosely a short tube I having an interior diameter somewhat more than the correspond ing filling pipe so that passage is formed between the lling pipe G and its surrounding tube I. Near the lower end of each tube I is secured or formed a fiange I2 on the under side of which abuts a ring I made of rubber or other suitable material and adapted to be seated in the mouth of the bottle as is plainly shown in Fig. 2. On the upper end of each tube I is secured a head J formed with the chamber J connected by the port J2 with the interior of the tube Gr and into the said chamber J extends the lower end of a vertically disposed float valve K held loosely inthe reduced extension chamber J3 formed in its top with a valve seat J4 opening to the outside and adapted to be closed at the inside of the extension chamber J3 by the valve K screwed or ICO otherwise secured iu the end of thehollowiffloat valve K as plainly shown in Fig. 4. An 'indie eating stem K2 extends upwardly from the valve K and passes loosely through the valve seat J4 to indicate the position of the valve K relative to its seat J4. In the side wall of the hollow fioat valve K are arranged vertically disposed grooves K3 to facilitate'the escape ot' 4the air from the chamber J through extension chamber J3 and seat J4. A

A spring L is coiled near the upper end of each filling pipe G, the lower end of each spring resting on the head J while the upper end is adapted to be engaged by the under side of the tank F on lowering the same as shown in Fig. 2 to compress the spring and to press the head J and its tube I downward to firmly seat the ring l on the mouth of the bottle.

In the head J above the tube I is arranged a suitable packing J5 fitting on the filling pipe G so as to hold the tube I in proper place by frictional contact with the filling pipe after the tension ot' the spring is released on raising the tank F and at the time the spring is fully released and extended as shown in Fig. l. The upward movement of the tubes I is limited on the return-or upward movement of the tank F by the flange I2 striking the under side of the guide plate A. On the guide rods E is fitted to slideloosely a centering plate N adapted to rest on pins E4 secured on the guide rods at the time the tank F and its guide rods are. in an uppermost position as shown in Fig. 1. Ou the under side of the centering plate N are arranged centering heads N having conical openings for the central passage of the filling pipes the said heads being adapted to fitinto the exterior surface of the mouths of the bottles so as to move the same into a central position for the ready entrance of the filling pipes G at the time the tank F is lowered.

The operation is as follows: When the several parts are in the position shown in Fig. l and the tank F is filled with liquid and a tray C with empty bottles is on the platform B then the operator in order to till the bottles with the liquid contained in the said tank F moves the latter downward whereby the guide rods move in the same direction and the centering plate N moves with its heads N' over the mouths of the bottles to properly center the same for the following filling pipes G and the rings I. The latter on the furtherdownward movement of the tank filling pipes and tubes I finally seat themselves in the mouths of the bottles lso that a further downward motion of the tubes I is prevented andthe tubes are held stationary. 'lhe filling pipes G move downward into the bottles on the further lowering of ythe tank, the said pipes now sliding through the tubes I and their heads J and as the springs L rest on the said heads J the downward moving tank nally engages the springs and compresses the same whereby the tubes are pressed and their fiexible 'ringslnally seatedY in the mouths of the bottles las will he 'readily understood by reference to Fig. 2. When thetank F is finally moving into its lowermost position then the rods H strike the bottoms of the bottles and the valves H are unseated to permit the liquid to flow through the filling pipes into the bottles to fill the same as previously described. W'hen the liquid iiows into the bottles the air therein retreats and passes upward .through the tubes I, port J 2, chambers J J3 and open valve seat J4 to the outer air. When the inflowing liquid has finally filled the bottles it rises in the tubes I and passes through the ports J2 into the chambers J in which the rising liquid liftsthe float valves K so that the valves K seat themselves onthe seats J4 thus preventing any outfiow of the liquid at the heads J and at the same time stopping furtherinflow ofthe liquid into the bottles through the filling pipes G. As the float valves rise the stems K'a move upward thus giving a signal to the operator that the bottles are filled. Now when all the stems K have moved into their uppermost position then the operator knows that the dow of the liquid through the filling pipes has ceased and he now raises the tank F and filling pipes G whereby the valves H seat themselves to close the filling pipes at their upper ends. As the filling pipes recede out of the bottles the small vamount of liquid in the filling pipes and in the tubes I and heads J iiow back int-o the bottles to take the place of the space occupied by the lower part of the filling pipes that had extended into the bottles. By this arrangement the bottles are filled close up to the necks and no liquid whatever is wasted. On the return or upward movement of the tankthe springs L are released so that the tubes I finally move with the filling pipes G owing to the frictional contactfof the packings J 5 with the said filling pipes. The pins E4 finally engage the centering plate N so as to lift the same clear o the bottles as shown in Fig. l to permit removal of the tray Ccontaining the filled bottles.

Having thus described our invention, what we desire to secure by Letters Patent isl. In a bottle filling machine the combination with a filling pipe connected with a liquid supply and adapted to pass into the bottle to be filled of a tube fitted to slide on the said filling pipe and forming a space with the filling pipe for the passage of the air and liquid, the lower end of the said tube being adapted to be seated on the mouth of the bottle while the filling pipe slides down in the tube and into the bottle, a head held on the upper end of the said tube and provided with a chamber connected with the said space and having a valve fseat and a iioat valve held in the said chamber and adapted to be seated on the valve seat in the said chamber substantially as shown and described.
